Spotted wing drosophila: devastating effects on cherry and berry pest management

R.A. Van Steenwyk, M.P. Bolda
Spotted wing drosophila (SWD), Drosophila suzukii, exploded into California berry production districts in 2008 and cherry production districts in 2009 causing significant economic loss for a number of growers with many growers experiencing complete crop loss. Starting in 2009 in berries and 2010 in cherries the economic damage caused by D. suzukii was kept to a minimum through repeated applications of broad-spectrum insecticides. Insecticide usage increased 4.8 fold in cherry, 3.5 fold in raspberry and 1.2 fold in strawberry from 2007 to 2012. The repeated use of broad-spectrum insecticides disrupted integrated pest management systems developed for cherry and berry crops. The repeated application of insecticides has had a serious impact on the beneficial arthropods and has resulted in an increased use of miticides. Miticide use increased 2.0 fold in cherry, 3.8 fold in raspberry and 2.2 fold in strawberry from 2007 to 2012. Potential control options that would be less environmentally disruptive are biological control, cultural control, mass- trapping and attract and kill methods of control.
